摘要： A closed circuit (13) is formed such that the upper ends of preinstalled refrigerant pipes (2A, 2B) in a refrigerant circuit are connected to each other through an upper connecting passage (11) and the lower ends thereof are connected to each other through a lower connecting passage (12). A refrigerant is charged into the closed circuit (13). In a separator (50) of the lower connecting passage (12), a separating heat exchange coil (52) heats the liquid refrigerant to evaporate it, and a filter (53) captures foreign substance from the gas refrigerant. Two conveying heat exchangers (7A, 7B) of the lower connecting passage (12) alternately carry out a repetitive cooling operation of cooling the gas refrigerant, having been changed in phase by the separator (50), to change the phase from gas to liquid and a repetitive pressurizing operation of pressurizing the liquid refrigerant by heating the refrigerant to the extent kept in the liquid phase, respectively, thereby applying a running force to the refrigerant. The refrigerant cleans the preinstalled refrigerant pipes (2A, 2B) in a manner of circulating in the closed circuit (13) from the conveying heat exchangers (7A, 7B).

摘要： This refrigerant recovery system is provided with recovery piping 2, heat exchangers 25, 26 and check valves 30, 31, 37, 38. A refrigerant within the recovery piping 2 is heated and cooled by the heat exchangers 25, 26, so that a fluid power is imparted to the refrigerant. This fluid power is regulated to one direction by the check valves 30, 31, 37, 38, by which the refrigerant is transferred in one way within the recovery piping 2. Thus, the refrigerant can be recovered from a gas line 3 and a liquid line 5 with high efficiency. Also, a degassing circuit 306 makes the gas refrigerant within the recovery container 71 merged with the refrigerant within the recovery piping 2 cooled by the heat exchanger 25 or 26, by which the recovery container 71 can be degassed. Also, the refrigerant can be recovered to the recovery container 71 smoothly, so that the refrigerant can be recovered efficiently.

摘要： A piping cleaning system switches over a four-way switching valve 43 of a heat pump circuit 200 so that two transfer heat exchangers 25, 26 are operated alternately as a cooling device and a heating device, by which a cleaning refrigerant in a cleaning circuit 2 is circulated through a gas line 3 and a liquid line 5. During this cleaning operation with the cleaning refrigerant circulated, when the cleaning refrigerant runs short in amount, a solenoid valve SV3 is opened so that cleaning refrigerant of the refrigerant cylinder 71 is resupplied through a refrigerant resupply line 72 to either one of the transfer heat exchangers 25 or 26 that is cooling. On the other hand, when the cleaning refrigerant is excessive, a solenoid valve SV4 is opened so that the cleaning refrigerant is returned to the refrigerant cylinder 71 through a refrigerant bleed line 73. Thus, the amount of cleaning refrigerant can be maintained at an appropriate level.

摘要： A system for controlling operation of a refrigerating device which includes a refrigerant circuit (9) in which a compressor (1), a condenser (6), a receiver (4) for storing liquid refrigerant, a pressure-reducing valve (5), and an evaporator (9) are connected together, and a cycle changeover mechanism (2) for changing a refrigeration cycle of the refrigerant circuit (9) between forward operation and reverse operation, the refrigerating device being of such arrangement that the pressure-reducing valve (5) is positioned downstream of the receiver (4) during either one of the refrigerating cycles. The system prevents liquid back-flow to the compressor at the time of a cycle changeover, while allowing the refrigerating device to have accumulatorless construction. The top portion of the receiver (4) is connected to a liquid line on the downstream side of the pressure-reducing valve (5) through a bypass path (4a), and an on-off valve (SV) is provided in this bypass path (4a). The on-off valve (SV) is controlled to be opened for a predetermined time before the cycle is switched to a reverse cycle defrost operation. With this arrangement, a liquid refrigerant is recovered by the receiver (4) to prevent liquid back-flow. The on-off valve (SV) of the bypass path (4a) is opened during the reverse cycle defrost operation, but only from the time at which defrost has already progressed to a certain extent until the completion of defrost. With this arrangement, an excessive reduction of the low pressure and the liquid back-flow are prevented.
